Hi Jose,

Linux is always better. :D I can't speak to the plans for if/when VMD
will compiled for 64 bit windows, but I do know that 90% of the VMD
power users I know (an admittedly biased pool) use some distribution of
linux when running VMD (the other 10% run Macs). In terms of distro, if
you choose to go down that path, it mostly boils down to personal
preference, as the install procedure and running VMD itself are
identical across distributions. If you are serious, I'd make a few
virtual machines first to see which environment you like first, as
different distros use different graphics managers that may drive you
crazy when it comes to day-to-day usability. VirtualBox is a good
program for playing with virtual machines, as its free, making the total
cost to try this out $0. It is also possible to run VMD from inside a
virtual machine. You won't be able to use CUDA, but at least you can get
around the 32-bit size limitations if you install a 64-bit operating system.

Good luck!
